Been workin on my TR86. Need to replace the sprockets that couple together at the rotor gearboxes. Have the gearboxes all apart and sprockets ordered but can not figure out how to pull the tail piece outta the rotor shell. Got half a dozen 1/2" and half a dozen 3/8" bolts out but cant pull her. Even took off the nose cone and still can't figure out what the trick is. Is she just stuck? When I have time if I don't get a good answer I am gonna use some serious forces to pull on her but would rather know for sure that it is just stuck and I am not missing a bolt or weld or something. Thanks in advance!
